Triterpenoid saponins from the root of Weigela florida

Plants belonging to the Weigela genus are traditionally used flourish gardens, homes, and other living areas. This contains ten species that mainly found in Asia, but many cultivars have been cultivated around world. Previous studies on some of this revealed occurrence triterpenoid saponins, which possess interesting biological activities such as cytotoxicity, anti-complementary activity, anti-inflammatory activity. Based suggestion, a phytochemical study roots W. florida “Jean's Gold” was carried out using different chromatographic methods, spectroscopic analysis 1D- 2D-NMR, mass method (HRESI-MS negative mode). The isolation three known oleanane-type saponins olean-12-en-28-oic acid, 3-[(O-β-D-xylopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-O-β-D-xylopyranosyl-(1→3)-O-6-deoxy-α-L-mannopyranosyl-(1→2)-β-D-xylopyranosyl)oxy]-, (3β)- (compound 1), 3-[(O-β-D-xylopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-O-β-D-xylopyranosyl-(1→3)-O-6-deoxy-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl)oxy]-, 2), 3-[(O-α-L-arabinopyranosyl-(1→3)-O-[α-L-xylopyranosyl-(1→4)]-O-β-D-glucopyranosyl-(1→4)-O-β-D-xylopyranosyl-(1→3)-O-6-deoxy-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl)oxy]-, 3). Full characterisation presented gives better understanding phytochemistry ornamental plants, can be further for medicinal purposes.
